Homework Statement
Two slits are separated by 0.260 mm. A beam of 500 nm light strikes the slits, producing an interference pattern. Determine the number of maxima observed in the angular range -31.0° < θ < +31.0°.
Homework Equations
i used dsinθ = m(lambda)
The Attempt at a Solution
i used the formula above and got
(.26 x 10^-3)sin(31) = m (500 x 10^-9)
i got m as 267.82, but since there are 267.82 maxima to the right, and 267.82 to the left and one at m=0, that makes for a total number of 536.64 maxima
